Thanks for the link - that confirms that it is Indiana Glass as I thought and not Tiffin. Also it appears that it is a cordial and not a wine goblet. Was hoping to find out more about the metal too. Is it a Russian coat of arms? and was it put on by the manufacturer? and who was it done for?

Hi, I did some looking. It seems that it is a two headed eagle. The problem is finding one like yours. Also I think your glass is brown more than amber. Perhaps you have a rare Adams & Co. piece? I would guess your glass was made to order, not production. Good luck : )

Thank you for taking the time to look I have looked at Adams and Co and note that they merged with the United States Glass Company in 1891 and consequently that company was bought by Indiana Glass so the jury is still out on this one. Could be any of them I guess.

You can stroke Adams & Co. off the list of possible makers. They were the originators of the pattern with production commencing in late 1890 but neither they nor US Glass (who purchased Adams & Co, in 1891) made it in amber during its initial 19th century production period. The pattern made a reappearance around 1950 being made by both Tiffin (formerly US Glass) and Indiana in various colours and forms. Your stem was made in the mid to late 20th century.

I am sure that there is a way to distinguish but I don't have that knowledge. My interests in glass are largely 19th century and not this mid to late 20th glass. I would suggest that you join the Elegant and Everyday Glass Forum http://chataboutdg.com/forums/ and post this piece.
